Before the error occurs, check if the fan below rotates, and if the fan does not rotate, take the following steps.
※ While checking the nozzle, if necessary, refer to '5. Maintenance' and '4.4 Nozzle Replacement' in the User Manual to remove and assemble the nozzle.
1. Visually check for alien substances. (Filament Debris, etc.)
Visually check alien substances inside the fan and if finding any alien substances, remove them with tweezers.
※ Note that the white-black-red color line in the photo below is a fan harness.
They are not alien substances.
2. Check if it spins by hand
Spin the fan by hand and check if there is any noise or interference.
(Compared to the normal fan in the nozzle)
3. Check if EC error occurs after power on
[STEP 1]
1-1. Check the nozzle number where the problem occurred and select the extruder menu.
1-2. Wait until the nozzle temperature reaches the target temperature.
1-3. Through the extruder operation mode, transfer filament about 50mm in the direction of inserting the filament into the nozzle.
(Select the nozzle where the problem occurred, select the transfer length 50)
1) If the filament is ejected, continue printing. If the problem persists even after, proceed to [STEP 3].
2) If the filament does not exit the nozzle, proceed to [STEP 2].
[STEP 2]
2-1. Remove the snap ring on the top of the nozzle, remove the tube, and transfer it about 50 mm in the direction of inserting the filament into the nozzle, using the extruder menu.
2-2. Check if the filament moves in the direction to nozzle.
For details on how to disassemble and assemble the snap ring and tube, refer to Chapter 5, “1.5 Cleaning the Nozzle Inside”.
1) If the filament moves in the nozzle direction, cut off the thick part of the filament end obliquely, reassemble the tube and snap ring, and proceed to [STEP 1] again. If the filament ejection is still not possible through the nozzle in [STEP 1], proceed according to “1.5 Cleaning the inside of the nozzle” in Chapter 5 of the User Manual.
2) If the filament does not move, proceed as follows.
ⓐ Select a cartridge which number is same as the trouble encountered nozzle's number and proceed unloading.
ⓑ Remove the cartridge from the printer.
ⓒ Open the cartridge and check if the filament is twisted.
If there is no problem inside the cartridge and the filament cannot be transported in [STEP 2], contact the customer service.
[STEP 3]
3-1. Proceed to "1.5 Cleaning the inside of the nozzle" in Chapter 5 of the User Manual.
3-2. If notification 601 occurs, clean the encoder with the encoder cleaning brush as shown below. (When notification 401 occurs, only the inside of the nozzle is cleaned.)
3-3. Remove the snap ring from the tube holder of the nozzle and remove the tube.
3-4. Put the encoder cleaning brush inside the tube holder and move it up and down about 10 times to clean it.
3-5. After cleaning, insert the tube again and fit the snap ring.
For details on how to disassemble and assemble the snap ring and tube, refer to Chapter 5, “1.5 Cleaning the Nozzle Inside”.
1. Before loading the cartridge, make sure the filament does not stick out of the cartridge (at least 2 mm away from the end of the tube)
2. Before loading the cartridge, make sure the tube does not stick out of the cartridge (at least 2 mm away from the end of the tube)
If the tube is sticking out of the cartridge, please push the tube back into the cartridge case.
The tube should be about 2 mm inside the cartridge case as shown in the image below.
3. Make sure the flag is moving naturally (Refer to the linked video. )
DP200 normal flag motion video
3DWOX1 normal flag motion video
Please remove impurities which disturb the flag movement.
Please follow checklist below.
Cartridge mode (EC 411/412) : Step 4 ~ Step 6
Open filament mode (EC 611/612) : Step 1 ~ Step 5
1. Check the filament loading position referring to the image below.
Normal state Abnormal state
2. If you use the cartridge case with wide 3rd party filament
spool, it can make the problem.
Some of the 3rd party filament is wider than cartridge case so filament transfer will be disturbed.
3. Please check the diameter of filament. It should be 1.75mm.
4. Filament in tube
Can you see the filament in the red circled area?
If you can see the filament, please remove the filament by following the FAQ.
http://3dprinter.sindoh.com/support/faqs#1192
If you cannot see the filament in that area, twist the brass fitting and remove it.
After removing the brass fitting, can you transfer the filament without clogging?
In this state, you can manually push the filament from loading area so that help the extruder works.
5. Flag
Make sure the flag is moving naturally.
Sample video link : DP200
If the flag doesn't move naturally, please remove the impurities which disturb the flag motion.
Please pull out the filament or impurity by using long nose
pliers.
6. Cartridge check
1) Check if the gear in cartridge rotates well.⇒ If not, open the cartridge and check if there is a tangle of cartridge.
2) If yes, turn the gear until the filament comes out from cartridge. ⇒ If the filament doesn't come out, open the cartridge and check if roller holds the filament or not.
3) If the filament comes out, pull out the filament about 50~60mm, and cut it. ⇒ Re-install the cartridge and load again.
*Be careful for the end tip of filament to have the shape like the below after cutting.
If the problems persist, please contact the Customer Service.

Follow the UI instructions and start the auto recovery process, after the recovery process if problem persists follow the below steps.
(If the problem persists after following the all three steps, please Contact Us.
And let us know which step did you failed at first among three steps. )
1. Vulnerability in the Air Gap
When printing a model with a large bottom surface, it is highly unlikely to create the air gap between the raft and the main printout uniformly on all parts of the bottom surface.
This non-uniformity of the air gap can partially cause the following problems.
1) Difficult to remove the raft due to excessive close contact between the raft and the output (small air gap)
2) The output bottom surface is uneven or shrinking due to weak adhesion between the raft and the output.
In addition, in the case of cross-printing mode using dual nozzles, if the nozzle that prints the raft is different from the nozzle that prints the output, the possibility of such a problem increases.
